D600 SD card? & Picture style?

Quick question just to clarify. Ive ordered a D600 and would like to know if the 16/32GB SanDisk 45MB/s will be perfectly fine in terms of capturing the best possible video quality? Or if i will need to go to 95MB to achieve that? Quality in the sharps but also best quality so I can grade it in Color for example.

Will the 45MB/s or even the 30MB/s be OK for just photograph purposes? If the only difference is download times that's not to much of a bother to me.

Also, does any body know of any picture styles that will work well with the D600 in terms of maximising color grading flexibility?

Sorry if there newbi questions but the clarification will put me at ease,
